. ing'had therein to the accompanying drawmgs.

This invention has relation to dumpingwagons, and relates in particular to that class of dumpingavagons wherein the bottom of the Wagon is composed of two hinged sections, the sections being hinged to the sides of the body or frame of the Wagon and with their free edges meeting on a line running longitudinally of the wagon at the center thereof.

In a wagon constructed according to my invention I propose to provide one of the hinged sections of the bottom with a metal plate, which when the sections are in closed position will overlap the meeting edges of the two sections u on the u )er side so as to P Pl prevent the contents of the wagon from falling or siftin through the space between the meeting of t e adjacent edges of the two sec.-

tions, and as this plate is carried by one of the movable sections of the bottom it is necessary that the section carrying the plate should close before the other section; otherwise the I requiredclosure of the two sections in the proper position could not be secured, and I ave therefore provided novel means for closing the two sections of the bottom, whereby that section which carries the plate will always be closed first.

- The novel means which I have provided whereby one section of the bottom will 2.1-

ways be closed prior to the closing of the other section is also applicable to hinged bottom sections wherein the plate above referred to is dispensed with, and in this connection the said novel means for closing the bottom sections prevents the free edges of the same commg together and locking 'tlon before they have reached their proper in an angular posihorizontal position against the body or frame Will be developed in the of the wagon.

Another object of my invention is to pro vlde, 1n connection with the above-menltioned means for closing the hinged bottom sections, novel means for locking and releasing the closing means. Other objects and the means whereby they are accomplished following s conication; and my invention consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed.

Referring to the accompanying drawings, illustrating my im rovements, in the several figures of which line reference-numerals designate corresponding parts, Figure 1 is a side elevation of a dumping-wagon constructed according to my invention. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a vertical transverse sectional view on the line ac 0c of Fig. 1. Fig. 4 is a rear elevation of the same. Fig. 5 is a fragmentary detail sectional View of the winding and releasing mechanism for the bottom-closing means on an enlarged scale. Fig. 6 is a fragmentary view showing in elevation the mechanism shown in Fig. 5. Fig. 7 is a fragmentary side elevation of the brake mechanism of the wagon. brake mechanism shown in F ig. 7 Fig. 9 is detail perspective view of the brake-lever. Fig. 10 is a fragmentary detail view,.on an en larged scale, of a portion of the front end of the Fig. 8 is a top plan view of the wagon and of the movable bottom sections,

and Fig 11 is a similar view of a portion of the rear end of the wagon and of the movable bottom sections.

The side boards or frames of the wagon(desi 'nated 1 in the drawings) are mounted on a front axle 2 and a rear axle 3, and these axles carry, respectively, front wheels 4 4 and rear wheels 5 The side frames or boards 1 1 of the wagon are provided with a front board 6 and a rear or tail board 7, these parts being angularly disposed and permanently secured to the side boards or frames 1 1 by metal anglestrips 8 9, respectively.

Above-the side boards or frames 1 1 and the front board and rear board 6 7 are mounted side'boards 10 11 and front and rear boards 12 13, the side boards 10 11 and front boards 12 13 being an upward extension of the wagon-body and being united thereto by bent bars 14, which latter also constitute members of the hinges by which the movable bot tom sections are united. to the frame or body of the wagon.

The movable bottom of the wagon is composed of two hinged sections, (designated, respectively, 15 and 16, the section 15 being hinged to the straps 14 on body by means of hinged members 15, while the section 16 is hinged to the straps 14 on the. other side of the body by hinged members 16'.) The bottom section 15 carries a ioo one side of the 1 5 drawings.

50 boards or frames 1 1.

metal plate 17, that is rigidly secured upon the upper surface of said section and. extends from end to end thereof, and also extends somewhat out beyond the edge of said 5 section 1.5, so as to overlap the adjacent edge of the section 16. Along the under side'of the section 15 and adjacent the inner edge thereof is fixed a beam or brace 18, and along y the edge of the section 16 a similar bea'gn'tor to brace 19 1s fixed, these beams or braces projecting at both ends slightly beyond the ends of the sections 15 and 16 and the beams :01 braces being thicker at their middle than at their ends, as clearly shown in Fig. 2 of the The beam 18 carries on its forward end a sheave 20, which is rotatably mounted in a bracket 21, and on its rear end an eyebolt 23, these parts being employed for the reception and guidance of a chain 2%,

20 which serves, in connection with mechanism hereinafter described, as the means whereby the movable sections of the bottom are closed. The beam 19 is formed with a v ertical groove at its front end, a staple 25 25 spanning this groove, and with a similar vertical groove 26 at its rear end and a staple 26 spanning the groove 26, and with. a staple 22 at its center, said grooves and staples serving to receive and sustain in proper position the chain 24, above referred to.

Upon the outer surface of the front board 6 a bracket 27 is arranged, and in this bracket is journaled a sheave 28, over which the chain 24 passes, and a bracket 29 is carried by the rear board or tail-board 7, and in the bracket 29 is journaled a sheave 30, the chain 24 also passin g over the sheave 30. The co urse of the chain. 24 is as follows; Beginning with the eyebolt 23, to which the chain is attached,

4o the chain passes over the sheave 3t) and then "down over the rear end .of the beam 1) through. the staple 2G thence along the lower surface of said beam 19 and in. contact with the said surface through the staple 'up- 5 wardly through the groove 25 and staple 25 on the front end of the beam, thence over the sheave 28 and around the sheave 20 on the end of the beam 18 and thence up and around a roller 31, which is journaled inthe side The chitin, it will be observed, passes over but one sheave on the hinged bottom sections, this fsheave being carried by the beam 18, and it will also be ob-- served that the chain is in frictional con tact 5 5 with the lower surface of the bea'in 19 through the length of that beam, and this arrange ment is of particular importance for the reason, as will be hereinafter shown, that this frictional contact of the chain with the sur- 6:: face of the beam 19 has a controlling ellect upon the successive closing of the bottom sections.

The roller 31. carries a ratchet-wheel 32 at one end, the ratchet-wheel being fast on the 5 roller, and a lever 33, having a suitable haudle 3-1, which is mounted. on the roller between the ratchet-wheel 32 and the adjacent side bpard or frame 1. The lever 33 carries a pivotally-inounted swinging pawl 35, that is adapted to engage the teeth of the ratchetwhecl 32, and-a pivoted dog 36 is mounted in a bracket 37, that is attached to the endboard 6. The do is formed with a shoulder 37 at its free end that engages the teeth of the ratchet-wheel and is also formed with a tremit Y which In is ada ted at a certain osition of the lever 33 to strike the lower e ge of the dog 36 and raise this dog out ofengagement with the ratchet-wheel 32.

' A suitable brake is provided, this brake cmnprising a rockshaf t 13, having forwardlyextending arms 44 14, that carry brake-shoes 15, engaging the rear wheels 5. The rockshaft 43 carries a lever 46, to which is attached a rod 17, extending to the front of the wagon and there attached. to a pivoted lever 48, which is arranged so as to move in a slot 49 in a bracket 50, said slot. being provided with teeth 51 on one edge that are engaged by a tooth 52 on the lever 48,

The parts constructed and arranged as above described are operated in the following manner: When the wagon isloaded and the bottom sections closed, the latter are maintained in their closed position through the medium of the chain 24:, the roller 31, and the parts appurtenant to the roller. These appurtenant parts are best shown in Figs. 5 and 6, and, referring now to these figures, it will be observed that the dog 36 is in engagement with the ratchotovheel 312 and is held in locked position by the pin on-the lever 33, which in the position of the lever shown in full lines is one at a slight angle to the perpernlicular. In this position of parts the pawl 35 is inactive and rests upon one of the teeth of the ratchet-wheel 32. Now if it be desired. to dump the load from the wagon the pawl 35 is lifted by the hand and the lever 33 is moved around in the direction of the long arrow to a horizontal position, and, as.

shown by the short dotted lines in Fig. 5, the lug or proJection 42 toward the ends of the movement ol the lever to tins position engages the lower surface of the dog 36 and over the nose 38 of the dog 36 tions portion of the chain will unwind and the movable sectionsof the bottomto drop down and discharge the load.

When it is desired to close the movable secofthe bottom, the lever 33 is raised to a position above the horizontal position, preferably to the position shown by the long dotted lines in Fig. 5, this movement of the lever permitting the dog 36 to dro down into engagement with the ratcheteel. The pawl is also allowed to drop into engagement with the ratchet-wheel, and upon moving the lever 33 alternately in opposite directions the ratchet-wheel will be rotated through the medium of pawl 35 and dog 36 and the chain 24 will be wound up on the roller. The first few movements of the lever 33 will take up the slack of the chain between the sheave 28 and the roller and will raise the bottom section 15 to a horizontal position previous to any movement of the bottom section 16, the reason for this peculiar and novel action being that the portion of the chain 24 assing under the bottom of the beam 19 in h-ictional engagement therewith is less readily movable than the portion that extends between the sheave 28 and the roller, and consequently the last-named first be wound upon the roller and will elevate the section 15 before any inovement'is imparted to the section 16. After the bottom section 15 has been raised to the horizontal position shown in full has in Fig. 3 the continued movement oi the lever 33 will result in further windin of the chain upon thefroller 31, and eventual? when all the slack of the chain has been ta en up the section 16 will be brought up to a horizontal position and into contact with the lower the jolting of surface of the plate 17, carried by the section After the bottom sections have been closed by the operation of the lever 33 in the manner above-described the lever is thrown" position. shown in full lines in over into the 5, thereby locking thedog '36 in engage- -ment with the ratchet-wheel 32 and preventing accidental disengagement of the; dog by means than the movement of the lever 33 to a position where the in 40 is removed from above the nose-38 of the dog 36. Accidental movementmf the lever is somewhat guarded against by the upturned outer end 39 of the 1' olting movement own upwardly-by the upward-movement o1 by such j olting and would be thereby thrown in front of the pin 40 and tend to prevent the lever 33 'from assuming a vertical position.

' observed that it '60.

From the foregoing "description it will be is impossible in closing the bottom sections to close the section 16 until after. the section 15 has been'closed, and this feature is of particular importance whetheror not the section 1 5 is provided with the lapping plate 17, as otherwiseif the two movwere moved simultathe wagon or by any other,

the ldOg produced sition relatively to the bottom of the frame just before reaching their lull closed horizontal position and to ,j am at this position, leavmg a triangular opening at each end, which after the wagon is loaded would permit of the escape of its contents.

In Fig. 3 of the drawings I have shown the section 15in dotted lines in one of the positions which it assumes while being closed, the direction in which it is closed being indicated by a dotted arrow, and in the same figure of the drawings I have shown the section 16 in dotted lines in the position which it retains during the closing movement of the section 15, and the section 16, it"is to be understood, will retain the position shown in dotted'lines in Fig. 3 until the section 15 is drawn up to the fully-closed position shown in dotted lines in this figure.

I am aware of the fact that a dumpingwagon has been constructed wherein movable bottom sections are operated by means of a chain arranged somewhat similarly to the manner in which I arrange the chain; but in the dumping-wagon referred to one of the movable bottom sections is provided with a single sheave and the other with a sheave at each end, and under this arrangement it is impossible to obtain the frictional engagement of the chain with one of the bottom sections, which, as above described, eliects the successive closing of the bottom sections.

I claim 1. In a dumping-wagon, the combination with a body portion, of two bottom sections, each hinged at one edge to the, body, a beam carried by the free edge of each bottom section, a sheave carried on one end of one of said beams, a sheave mounted at each end of the body portion, a roller mounted onthe body portion, means for rotating said roller,

and a chain connected at one end to the end of the beam which is provided with a sheave and passing over one of the sheaves on the body portion, thence down to the other of said beams, along the same in frictional contact with the lowersurface thereof, thence upwardly around the other sheave on the body portion, thence around the sheave on the first-named beam, and thence around said roller;

2. In a dumpin -wagon, the combination with a bod movable bottom sections hinged to the b0 y, and a chain connected to said bottom sections, of a roller to which said chain is connected, a ratchet-wheel carried by said roller, a dog pivotally attached to the body and enga said ratchet-wheel, said dog being provi ed with a forwardly-projecting nose, a pivoted lever, a pivoted pawl mounted on said lever, a pin carried by said lever and'adapted at one position of the lever to extend over the nose of the dog, thereby locking the dag in 'l'kgsgjm uewil Wm the ratch-evwheoL 3.
